Indicates the current weight distribution The information entropy of Indicates at a point in time Time Dynamic weight values ​​of dimensions, represents the entropy function, Indicates in After the update The weight value of each dimension, Indicates that the right side is the value before normalization. represents the natural exponential function, represents the learning rate, Represents the loss function for the current The partial derivatives of the dimension weights.

10. The intelligent assessment system for rheumatic disease rehabilitation based on the ICF concept and classification system according to claim 9 is characterized in that: The operation process of the closed-loop feedback module includes: Iteratively update the causal pathway network by using a policy gradient-based reinforcement learning algorithm to obtain a pathway selection strategy based on the patient's long-term evaluation results and radar chart ,expression: Where, Indicates the The patient's real feedback vector at each time point, Indicates the The system predicts the output vector at each time point, Representation Strategy The total expected return, Indicates that in the strategy The expected value under Indicates from arrive The summation symbol, Represents the discount factor Power, Indicates the discount factor value , The smaller the difference between the evaluation value and the actual feedback, the higher the reward. represents the penalty term coefficient, The Kullback-Leibler divergence measures the difference between two probability distributions. Indicates the current time The causal path network constructed, Indicates the last moment The causal path network of The greater the deviation between the current path network and the previous path structure, the higher the penalty.
